AIR-CONDITIONING APPARATUS.

`Application filed September My invention relates to air conditioning apparatus and particularly to apparatus for conditionin the ar which is supplied to the cylinders o an internal combustion engine.

The invention has among its other objects the production of apparatus of the kind described, which is compact, convenient, durable, efficient and satisfactory for use whereever found applicable.

One form of the invention is embodied in apparatus which is particularly adapted to be used in conditioning the air supplied to the internal combustion engine of an automobile or the like. The apparatus comprises a housing which communicates with the 1n takey port of the carburetor of the engine.

The housing also communicates with a csing mounted upon the exhaust manifold of the engine, `the casing being open tothe atmosphere so that air ma be drawn into the housing through the casing and thence into the carburetor. The air then' passes through the carburetor and into the intake manifold of the engine. Disposed in thehousing is a perforate cage containing porous or fibrous material which is moistened by -water drawn from a receptacle 7disposed at any suitable oint within lthe hoodv of the automobile. eans is provided for controlling the flow of water to the cage.v

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and oo mbination of parts herein shown and described, and more particularly pointed out in the claims. e v

tion engine which comprises an intake manifold'll and exhaust manifold 12. As illistrated, the internal combustion engine 10 is of the type usually employed in automobiles and the like, the dash of an automobile being indicated at 14. Communicating inthe usual manner with the intake manifold 11 is a car buretor 15 which has its intake port connected to a housing 17 by a bent tube 18. The housing 17 `is substantially cylindrical in form and is provided with a cover 19. Formed integral with the cover 19, or mounted thereupon, is an elbow 2O which is connected by a pipe or tube 22 to a casing 23,

the casing 23 being secured to the exhaust manifold 12 by means which may comprise U-shaped brackets 24 or the equivalent. The

casing 23 Vis substantially arcuate in form and together with the exhaust manifold 12 provides an arcuate' chamber 25 which communicates with the atmosphere. Obviously,l

undesirableto heat the air drawn into`V the cylinders of the engine. The tube 22 may then be removed from the apparatus whereupon air will be drawn directly into the hous- 1 33 having a central vaperture 35 adaptedto receive one end ofla pi e 36V `which projects through lthe housing 1 The other end of the pipe 36 terminates in a receptacle 37 adapted to hold a supply of water. The pipe 36 is provided with valves 38 andl 39 inter- `mediate its ends for a purpose which will presently appear. The cage 30 provided with a plurality of legs 40 whichhold the cage spaced from a bottom wall4 1 formingpart of the housing 17. To hold the cage 30 centrally disposed in the housing 17 and to prevent rattling thereof within the housing, I preferably provide the cage with a plurality of laterally projecting members 43, as illustrated in Figs. 2 and 3.

Fixed Within the cage 30 is a perforate tube which preferably extends from the cover 33 to the bottom wall It will be noted that the pipe 36 projects into the perforate tube 45. The annular space formed between the perforate tube 45 and the cylindrical wall 3l is filled with any suitable substance 47, such as asbestos or the equivalent. The asbestos may be made up in a single piece having suliicient porosity to permit water to pass therethrough, or flake asbestos may be packed into the cage. In practice, the asbestos 47 is moistened with water obtained from the receptale 37, the flow of water from the receptacle being controlled by the valves 38 and 39. The valve 38 may be adjusted to permit a predetermined quantity of Water to flow through the pipe 36 per unit time. The valve 39 may be manipulated to close the passage through the pipe 36 whenever the engine 10 is not in operation, or whenever the operator deems it best to stop the supply of water to the cage 30. As shown in Fig. 1, I preferably provide a Bowden wire 48 extending from the valve 39 to the dash 14 so that the driver may adjust the valve 39 Without leaving hi seat. as, The bottom wall 41 of the housing 17 is preferably provided with a plurality of perforations 41a. Projecting through' the bottom wall 41 is a tube 41b which communicates with the bent tube 18. It will be noted that the tube 41b projects into the housing 17 in such manner that it forms an annular pocket 41c within the housing adapted to collect water which may drip from the cage 30. This construction prevents Water in an unvaporized form from entering the carburetor 15, as water which drips into the annular pocket 41c will be discharged through the perforations 41B.

In the operation of the above described apparatus, the valve 38 is adjusted in the manner above described to regulate the fiow of water to the cage 30. The pipe 36 discharges the water into the tube 45 and it flows through the perforations thereof into the asbestos 47 which becomes suiliciently saturated so that air passing through the housing 17 is moistened, the moisture passing through the perforations provided in the cylindrical wall 31. A portion of the air will be drawn through the perforate cover 33 and through the moisture laden asbestos and thence into the bent tube 18. The moistened air will pass through the bent tube 18 into the carburetor 15 and thence through the intake manifold 11 to the cylinders of the engine. Any excess moisture or water which may drip from the cylindrical wall 31 will pass from the housing 17 by way of the apertures 41a provided in the bottom wall 41. The operator or driver may control the admission of water to the cage 30 by means of the valve 39.

The improved apparatus enables the driver to condition the air entering the carburetor so that the engine may be made to operate eiliciently and smoothly. Obviously the air may be heated if it is so desired, and the amount of water mixed with the air is readily controlled. 'lhe improved construction insures that only vaporized water will enter the carburetor.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:
